Performance
Performance has been tested on the Intel platform, including the i7-14700K processor, ASUS Z790 APEX motherboard, Colorful RTX4080 Advanced OC 16GB graphics card, Kingston Renegade 2TB NVMe SSD, and Corsair 1200W 80+ Platinum PSU.
All results were performed on the Viper Elite 5 64GB DDR5-6200 memory kit. Our stable overclocking limit was 7200MT/s, but overclocking is not guaranteed. At this clock, the memory could run at respectable timings of CL38-46-46 at the 1.45V VDD/VDDQ. The voltage is still suitable for daily usage, and memory modules shouldn’t overheat, but it’s recommended to have some airflow in the PC case.
We will start with the AIDA64 Memory and Cache benchmark, which is probably the best application to check memory bandwidth and latency.
The results in the AIDA64 benchmark almost always look better at higher frequencies, so it is no wonder that our overclocked settings give higher bandwidth. In this case, dual-rank modules help a bit with results. We wouldn’t expect such high bandwidth at the relaxed timings programmed in the XMP. It clearly looks better than in the general specifications.
The latency test shows how high the difference is between the XMP and overclocked settings. Over 70 ns at the XMP profile is not the best, but it’s also not bad compared to regular memory series like the recently reviewed Crucial or Crucial Pro with the 90 ns latency.
AIDA64 tests are fully synthetic and usually do not present real-world performance. The next tests should give a better view of the daily performance.
PCMark 10 already shows that the overclocking of our Elite 5 memory kit isn’t helping much. We can still see a bit better results in all tests, but it’s nothing that would affect our daily work.
The same story can be seen in 3DMark benchmarks. Overclocked settings are barely better.
Surprisingly, the new Cinebench 2024 gives us a higher performance gain than we expected. It still suggests that it is better to use the XMP than waste time on hours of overclocking and stability tests.
The same Final Fantasy XV and Superposition benchmarks have all results close to the error margin.
Results in games finally show something higher. Less demanding titles or low display resolutions can take advantage of faster RAM. More demanding games at high display resolutions push graphics cards to the limits and don’t rely so much on the CPU or RAM. Then, the FPS gain is not so significant. We can see that the average FPS in the Shadow of the Tomb Raider at 1080p can improve even by 20-30 FPS.
At first sight, the tested Viper Elite 5 memory kit doesn’t seem any special, but it’s pretty fast in all our tests. The general specifications are quite misleading, while our results in popular games are about as high as those of previously reviewed DDR5-6800 and DDR5-7200 memory kits.
I will tell you more about overclocking on the next page of this review.
